Survival, morphological variability, and performance of Opuntia ficus-indica in a semi-arid region of India

Cactus pear (Opuntia ficus-indica (L.) Mill.) can survive extreme environmental condition and is known for its fodder potential in many parts of the world. The morphological diversity of 15 introduced accessions was evaluated at Jhansi, Uttar Pradesh, India. The plants were established in 2013. Survival and nutrient status were evaluated after two years. Above-ground plant height, biomass, primary and secondary cladode numbers, primary and secondary cladode lengths and below-ground root length, weight, and surface area measurements were done six years after cladode planting. Yellow San Cono, White Roccapalumba, and Seedless Roccapalumba survived 100%. The discriminant traits according to principal component analysis were: primary cladodes plant−1 (component loading, 0.87), primary cladodes biomass (0.95), secondary cladodes plant−1 (0.83), canopy width (0.84), and plant biomass (0.92). Hierarchical cluster analysis grouped 15 accessions into two main clusters based on 17 morphological traits. Cluster I showed favorable values for many above- and below-ground morphological traits while Cluster II showed higher performance for root system width, height, and biomass, and primary and secondary cladode numbers. The results indicate that cactus pear accessions have considerable morphological variability and genetic diversity suitable for promotion as alternative fodder resources in semi-arid regions of India

Not AvailableSoil organic carbon (SOC) is highly sensitive to land use change and helps in maintaining soil quality. Changes in soil fertility status, SOC dynamics, and carbon indices were studied in a four - year experiment with nine sets of food - fodder cropping systems (CS) and three resource conservation techniques like rainfed (RC1), life saving irrigation (RC2) and in - situ moisture conservation practices (RC3). Results showed that the CS5 [Tri - Specific Hybrid (TSH) + Desmanthus virgatus+ (Sorghum + Cowpea Chickpea)] recorded the highest values 12.25 g kg1, 41.5 mg kg1, 3.5 g kg1, 289.5 mg kg1, 424.8 g g1 soil, 54.69% and 39.31% of total carbon (TC), hot water - soluble carbon (HWSC), particulate organic carbon (POC), labile carbon (LC), soil microbial biomass carbon (SMBC), humic acid carbon (HA - C) and fulvic acid carbon (FA - C), respectively. Among resources conservation practices, RC3 improved the SOC (56.16%) and other carbon fractions significantly as compared to RC1. Significant and positive correlations (P < 0.05) were found between carbon pools and available nutrients. The carbon management index (CMI) was also maximum (193) with CS5 and CS9 [TSH + Sesbania sesban+ (Sorghum + Cowpea Barley)] and RC3 (232). Therefore, promoting cultivation of food - fodder system with in - situ moisture conservation practices is considered as sustainable management option for sequester more carbon, sustainability and soil quality in rainfed semi - arid ecosystem

Spineless fodder cactus under different land use and production systems in rainfed semi-arid tropics of India

Spineless forage cactus can be a cost-effective solution for the livestock keepers of semi-arid tropics by providing a stable source of nutritive forage capable of maintaining healthy and productive herds/flocks especially during lean periods. Therefore, the feasibility of growing cactus as an alternate source of feed and fodder in different land use systems was explored for these areas. Spineless fodder cactus was planted under various land uses and production systems like boundary plantation in rainfed farming systems, silvopasture, hortipasture, intercropping with forages like tri-specific hybrid (TSH) and cowpea, waste lands and also on farmers’ fields. The growth and yield of spineless forage cactus was recorded at the one and half year-old stage. On average, cactus achieved 74.8 cm height with 13.4 cladodes plant‑1 and 7.95 kg plant‑1 fresh biomass in TSH based intercropping system. The fresh fodder yield from cactus, TSH and inter-cropping system as a whole was 79.5 t ha‑1, 106.34 t ha‑1 year‑1 and 185.84 t ha‑1, respectively. The survival, cladodes plant‑1 and green fodder yield of cactus in Leucaena based silvipastoral system ranged between 62 and 81%, 2-7 and 1.5-5.25 kg plant‑1 while the corresponding values for Emblica based hortipastoral system were 67-86%, 3-10 and 2.4-8 kg plant‑1. The boundary plantation of cactus in rainfed farming system recorded 84-96% survival, 4-14 cladodes plant‑1 and 4.8-16.8 kg plant‑1 green fodder yield. Similarly, the cactus planted on waste land recorded 73-92% survival, 3-12 cladodes plant‑1 and 2.7-10.8 kg plant‑1 fresh biomass. The cactus planted in boundary plantation system recorded higher growth and fresh biomass followed by grass inter-cropping and least under shade in silvipastoral and hortipastoral systems

Cactus Pear (Opuntia ficus-indica) Productivity, Proximal Composition and Soil Parameters as Affected by Planting Time and Agronomic Management in a Semi-Arid Region of India

Study of appropriate planting time and response to agronomic management practices is imperative for the newly introduced cactus pear (Opuntia ficus-indica (L.) Mill.) into a semi-arid region of India. Responses of cactus pear to agronomic practices (planting time and irrigation and fertilizer application) were evaluated to determine the potential for fodder production and livestock feed in a semi-arid environment of India. We assessed four planting times (February, March, July and October) and two agronomic managements (with and without irrigation and fertilizer application) during 2016–2020 at Jhansi, India. Cactus pear establishment and growth improved with planting time in July and October due to favorable soil moisture and congenial temperature. However, plant height (19 cm) and cladode weight (118 g) were greater in July than in October planting. Nutrient uptake and crude protein contents, however, were higher for the earlier plantings of February and April compared to June and October. Irrigation and nutrients application had little effect on the cactus pear plant growth, except on plant width and cladode length and width. Cactus pear can be planted during July in moderately fertile soils without any agronomic intervention in semi-arid situations of India and has potential as an effective alternative source of forage for livestock during the summer months
